Neck aneurysm symptoms?

summary

Carotid artery aneurysms are usually caused by arteriosclerosis, trauma, bacterial infection, syphilis or congenital cystic necrosis of the middle layer of the artery. The arterial wall becomes thinner and expands gradually under the effect of blood flow pressure to form aneurysms. Carotid aneurysms can occur in the common carotid artery, internal carotid artery, external carotid artery and its branches. Most of the cases caused by carotid arteriosclerosis occurred at the bifurcations of bilateral carotid arteries, and most of the cases caused by trauma occurred in the internal carotid artery, but rarely through the external artery. The main symptoms were neck mass with obvious pulsation and murmur. A few masses were blocked by layered thrombus in the tumor cavity, and the pulsation weakened or disappeared.

Neck aneurysm symptoms?

Common by arteriosclerosis, trauma, bacterial infection, syphilis or congenital cystic necrosis of the middle layer of the artery caused by arterial wall damage thinning, under the effect of blood pressure gradually expanded, forming aneurysms. Carotid aneurysms can occur in the common carotid artery, internal carotid artery, external carotid artery and its branches. Most of the cases caused by carotid arteriosclerosis occurred at the bifurcations of bilateral carotid arteries, and most of the cases caused by trauma occurred in the internal carotid artery, but rarely through the external artery.

The main symptoms were neck mass with obvious pulsation and murmur. A few masses were blocked by layered thrombus in the tumor cavity, and the pulsation weakened or disappeared. The blood supply to the brain can be affected by the common carotid artery and the artery passing through the internal artery. The thrombus falling off in the tumor can cause cerebral infarction. The patient may have some symptoms of cerebral ischemia, such as headache, dizziness, aphasia, tinnitus, memory loss, hemiplegia, dyskinesia, blurred vision, etc. The enlargement of the tumor oppresses the nerves, larynx, trachea and esophagus. Cerebral nerve paralysis, Horner's sign, dysphagia and dyspnea may occur.

matters needing attention

Pathological carotid aneurysms can be divided into three categories: ① true aneurysms: most of them are caused by arteriosclerosis, the aneurysms are dilated and expanded, most of them are fusiform, and most of the lesions involve the whole circumference of the arterial wall, with different lengths. The thickness of tumor wall is not uniform, and spontaneous rupture often occurs, causing massive hemorrhage; ② Pseudoaneurysm: it is mostly caused by trauma. The wall of the aneurysm is composed of arterial intima or surrounding fibrous tissue. The contents of the aneurysm are blood clots and organizations. The tumor is cystic and connected with the artery. The neck is narrow. ③ Dissecting aneurysm: it is mostly caused by congenital cystic necrosis of the middle layer of the artery. When the intima is ruptured, the blood flow forms a hematoma in the middle layer under the action of arterial pressure and extends to the distal end to form dissecting aneurysm.
